Hi, I want to buy a new microsd card for my sp3. It should be as fast as posible (read and write). I have read Sandisk Extreme Pro or Samsung Pro + should be fast enough (up to 95 MB/s and write at up to 90 MB/s. ). My questions are: -which are the fastest microsd cards atm with 64Gb or 128Gb capacity (read and write speeds are both important to me since it is going to be my data disk)..any links to reviews would be great! -I have seen most 128Gb microsd cards are labeled as sdXC (and I read they can only be formatted as exFAT). I read it while surfing the web, so I want to ask if it is really like that? Or can I format a micro sdXC-card as NTFS too and just handle it as a normal hard drive? Pls, let me know what you think based on your previous experience with such cards and SP3. Rgds.
